tune up consist of what

For normal driving, even to and from work or school, it should be between 30 to 50K miles. If you tow a boar or pull a trailer, or use it for work and hull heave stuff in dust and dirt, check it around 25K. Spark plugs should be good for 100,000 miles these days. Factory recommends a fuel system flush and injectors flush about 25 to 30K. The engine will tell you when the oil is dirty enough to change it. I've gone 14k miles between oil change because I don't drive in dust or dirt. On a long road trip, I got in dust storms and the change oil warning came on at 7k after that. Like Tom said, check you manual for times for services.
